To all whom it mag concern Be 1t known that I, JENs SIMONI, a subject of the Kin of Denmark, .and resident of Keyport, in t e county of Monmouth and.

State of New Jersey,-have invented a new and useful Improvement in Puncture-Healing Liquids for. Tires, of :which the followmg is a specification.

' This invention relates to a liquid composition intended to be inserted with-in pneumatic vehlcle tires for the instant healing of punctures, and. among otherjobjects, it is calculated to not only be free from substances which injurethe tire, but to actually beb'eneficial to. the rubber structure.

It is also adapted to lessen the heating effect of the friction upon the-tire while-the vehicle is in motion, to prevent the rubber from drying out, to instantly heal any puncture, thereby preventing the' escape of air and hence injury to the tire by use in a partially deflated. cfindition.

Further, it may be kept inany. convenient air-tight container and is very readily applied for use. v

The composition which is the subject-matthick inserted, in a predeterminedamount, within The method of putting the healing'liquid in the tire which I prefer, consists in re-' coarse grease gun.

the cavity-ofthe tire, and then, by means of centrifugal force generated during the motion of the vehicle, be caused to spread in a relatively thin film over the surface of the tire. In the case of a single tube tire, it is put within the tube, and in the case of a double tube tire, it is put within the socalled inner tube.

moving the valve from the tire and pouring the thick and viscous liquid therein through a funnel, or insertin it by means of a have found that a proper amountto be used consists in from about a pint and a half. to three pints for so far as the limitations are specified in the each tire according to the size thereof. The liquid includes among its components,

I asbestos, gum, acid and-water, and in the particular form whichI-prefer, it includes. asbestos fiber, asbestos rcement gum arabic, gum tragacanth, chromic acld and water.-

The best proportions of these ingredients of which I am aware at the present time as to be follows: four pounds of asbestos. fiber, ten

UNITED STATES PA ENT orFroE-if nanny cnm'xsou, or 7 Patented Sept. 1. 1914.:

ingredients, when mixed together, will make about fifteen gallons of the healing liquid. In mixing these ingredients I follows: The gum arabic is first 'ssolved in part of the water, which may be either cold;

or warm according to the weather and the desired speed of dissolving. The tragacanth is similarly dissolved by itself in part of the water. These two solutions of gum and water are then mixed together and the asbestosfiber, which has previously been carded and kneaded, is mixed in with the gums and water, together with an added amount of water suflicient to kee the mixture in the form of a liquid; T e asbestoscement s next added, together with some -#mor'e water, and finally the chromic acid is admixed in conjunction with the remaining roceed as p portion of water, and the whole thoroughly stirred. As indicated above, the water is added during the mixing in suflicient amounts to maintain the composition in a liquid, so that it canbe stirred.

The asbestos is a very valuable element for the reason that it tends to prevent undue expansion of the air within the tire while the vehicle is in motion and hence removes unnecessary strains from the tire structure;

- The chromic acid serves a very useful purpose; in causing a' rapid hardening of the .heahng mixture by contact with the -"at-- mosphere, while the proportion used is so small as not to sensibly injure the tire.

It will be understood that while I have described the articular ingredients and the proportions t 'ereof for the purpose of clearly setting forth the best way known to me in which the invention can be utilized, I do not intend to limit theclaims except in claims themselves; and hence -I do not consider my invention as being confined to the orth.

What I claim is:

particular ingredientsfand proportions set mic aci & bestos, gum, chromic acld and water.

4. A puncture healing liquid including asbestos, gum arabic, gum tragacanth, chroand water.

5. A puncture healing liquid consisting of 10 asbestos fiber, asbestos cement, gum 'arabic,

gum tragacanth, chromic acid and water.

6. A puncture healing liquid consistin of asbestos fiber, asbestos cement, gum ara ic,

gum tragacanth, chromic acid and water in substantially the following proportions: four pounds asbestos fiber, ten pounds asbestos cement, three pounds gum arabic, one-tenth pound tragacanth, one-fourth pound chromic acid and seventy-four pounds water.

In testimony that I claim the foregoing as my invention, I have si ed my name in resence of two witnesses, t is twenty fourth day of November, A. D. 1913.
